The French Breakfast radish (Raphanus sativus) is an heirloom variety radish and a member of the Brassicaceae or Cruciferae family.
While some varieties of the French Breakfast radish are round in root shape most are oblong and two to four inches in length. Whether round or cylindrical, the French Breakfast radish is known for its vibrant coloring which graduates from a vivid fuchsia-red to bright white at the tip. Topped with edible, leafy greens, French Breakfast radishes are very crisp and offer a mildly spicy flavor. Grilling or oven roasting will bring out the subtly sweet and nutty flavor of the French Breakfast radish.
French Breakfast radishes contain Vitamin C, calcium, magnesium, folate, and potassium. Natural medicine practitioners recommend radishes for their ability to promote healthy digestion. French Breakfast radishes also contain glucosinolates, which have been shown to be beneficial in the prevention of certain cancers and are what give radishes their distinct peppery flavor.
